Application nea october 1, 1894.. serai No. 524,570. no man.)

To a/ZZ whom it may :baraccwmVV Be it known that I, FRANKLIN S. RANDALL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Spinning Fiber on Wire; and I do declare the following to be a full, clear, and,

z o feeding rolls for introducing the straightened fibers to thewire, a device for combing the ,surface bers around it, and means for lashing the straightened fibers evenly to it. g

In the drawings attached, Figure lis a front 2 '5 elevation of the machine. Fig. 2 is a detached side view of the drawing and feeding rolls and otherimmediately associated parts. Fig.

3 shows in broken lines a form of Vgear-drive for the said rolls. Fig. 4 is a detached view 3o of the comb and a plan view of the winding apparatus.

Between the uprights A, A, near thebottom is represented the let-off reel w, supplied with the naked wire m, and near the top of 3 5 the standards is the take-up reel n, for receiv`V ing the covered wire. Directly belowpthetakeup reel n, are journaled in the frame A, the

drag-rolls p, and occupying a position lower down journaled in the cross-girts A', A', re-l 4o spectively, is the polishing device o, and the winding apparatus g. Both of these parts are driven from the power shaft h, by means of the belts 1 and 2.

The mandrel s of the winding apparatus g, is tapering on theinside from the bottom to the top, and the circular top plate .of this part is provided with a winding reel t and a comb o.

Mounted in any suitable manner in the frame of the machine below the mouth of the hollow tapering mandrel s, are the drawing and feeding rolls B, receiving their rotary motion by means of the train of, gearing d, actuated by a gear c', on the inner end of the power shaft la, which is revolved by means of the belt 4.

f A sprocket chain t, communicates positive motion to' the drag-rolls p, from one of the shafts by which the take-up reel fn, is driven by means of the belt 3.

In the placing of the liber e on the wire itis introduced into the' seriesv of drawing rolls B, inthe form of a strip of sliver coming from the receptacle u, and after passing through the series of rolls it is delivered to the vertically moving wire with its fibers straightened and drawn to the required amount necessary to cover the wire to the proper thickness. The upward movement of the wire fm, corresponding approximately to the delivery of the feed rolls, but being slightly greater than 4that delivery. l After passing through the said revolving hollow tapering mandrel they are then acted upon by a revolving comb o secured to the upper face of lthe revolving'circular plate carrying the reel t, which lashes the straightened fibers firmly and evenly around the wire. 1

`Y The lashing thread secures the fiber firmly on the wire during the necessary subsequent baths of the covered wire inthe insulating compound in manufacturinginsulated'wires..

` I claim- In a machine for placing parallel fiber longi-v tudinally on a wire the combination of a series of drawing and feeding rolls, a revolving plate having a hollow tapering mandrel said plate being provided with a winding reel and comb, means for drawing the wire through the-mandrel and plate and means whereby said parts are operated in the manner and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FRANKLIN S. RANDALL.
